Patent GB-2165013-A (GB)
Title: Vehicle anti-lock braking control
Inventor: BREARLEY MALCOLM
IPC: B60T8/1763
Filed: 1985-07-16
Abstract: A vehicle anti-lock brake control system includes wheel speed sensors (S1 to S4) which input speed signals to a microprocessor (11) via an interface circuit (10). The microprocessor is programmed to calculate the deceleration (eg 301, 302, 303) of each wheel, compare this with a variable threshold (300, 304) and output a signal to a brake release device (A, B, C) for as long as the deceleration exceeds the threshold. The threshold level is calculated by the microprocessor as a function of the time elapsed since the threshold deceleration is first exceeded. initially the threshold is relatively low, but rises in steps with time elapsed (300). After a predetermined time interval the threshold (304) falls to a new relatively low level which depends on the slip of the wheel and may be a low acceleration. If the slip of the wheel remains higher than a set level following re-application of the brake, a low "fast re-trigger" threshold level is established so as to release the brakes again rapidly if excessive deceleration is again detected or expected acceleration levels are not attained. <IMAGE>

Title: Remote reading of mechanical counting device
Inventor: LOKKERBOL DAVID HENRY
IPC: G06M1/274
Filed: 1986-02-20
Abstract: A gas meter has a counting device comprising parallel decimal and binary systems (20, 16) mechanically locked together. The binary index (16) sets up a binary representation by reed switches (15). A remote reading device interrogates the switches (15) in order to set up a display of the counted number. The binary output signals may be converted to a serial form to reduce the number of output lines which otherwise connect the remote reading device to the gas meter. <IMAGE>

Title: Air conditioning system and method of operation
Inventor: GLAMM PAUL ROBERT
IPC: F25B13/00
Filed: 1986-03-12
Abstract: An air conditioning system 10 has a compressor 14, an indoor heat exchanger coil 22, an outdoor heat exchanger coil 28, an accumulator 20, and two controlled valves 32 and 46. The valve 32 can be set to connect the compressor outlet line 34 to either of the coils 22 and 28, the compressor inlet line 21 then being connected respectively to the other exchanger coil. The valve 46 can be opened to provide unrestricted flow between the coils 22 and 28, or closed so that only restricted flow through one or the other of two bypassing metering valves 42 and 44 is possible. To transport condensed refrigerant quickly from one of the coils 22 and 28 to the other at start up of an operating cycle, the valve 46 is temporarily opened and the valve 32 set to allow the compressor to blow the condensed refrigerant from the one coil to the other. <IMAGE>

Patent GB-2195262-A (GB)
Title: Wine filtration
Inventor: HARRIS ROBERT EDWARD WILLIAM
IPC: C12H1/02
Filed: 1986-09-30
Abstract: A method of filtering wine, for use by home wine makers dealing with small volumes for example multiples of 5 litres, comprises the use of a thin cellulose/glass fibre pad or sheet which gives a fast flow during filtration, but which would, if used alone, quickly clog and become unusable. Perlite, diatomaceous earth, cellulose or glass fibres is added to the wine at about 1 teaspoon per demijohn (1:1000) and forms a filter bed which increases in thickness as the filtration continues, effectively providing a new filtration surface throughout the whole of the filtration operation.

Patent GB-2224568-A (GB)
Title: Fibre-optic continuity tester device
Inventor: TAYLOR PHILIP JAMES
IPC: G01M11/00
Filed: 1988-11-03
Abstract: A fibre-optic cable is connected between a transmitter unit (Figure 1) and a receiver unit (Figure 2). Light from a light emitting diode (8) in the transmitter unit is transmitted over the cable if it is continuous to be received by a light sensitive diode (12) in the receiver unit. This light activates the receiver unit and causes either a light emitting diode (18) or an acoustic sounder (20) to be activated to indicate continuity in the cable. The receiver unit circuitry may act as a filter to remove low frequencies, particularly those associated with a local power supply. The transmitted light may be pulsed at 3 kHz. <IMAGE>

Title: An accelerometric device in a moving vehicle
Inventor: SHARON R DAN
IPC: G01P15/08
Filed: 1989-05-12
Abstract: A signalling device is attached to a road using vehicle to indicate to other road users about the dynamics of the vehicle by using accelerometric information. When driving behind other vehicles, in particular on motorways where traffic is moving at high speeds, drivers can assess changes in the velocities of vehicles in front of them only through second order parameters, a thing which seriously delays their reaction to such changes. The accelerometric signaling device will indicate changes in the velocity of a vehicle, helping other drivers to adapt their own speed in accordance and in good time, e.g. a red light, 6 in Figure 2, will be switched on as soon as the vehicle starts decelerating, turning into a flashing light for accentuated deceleration. A green light, 8 in Figure 2, will turn on when the vehicle is accelerating, and a white light, 7 in Figure 2, will be on for constant velocities. <IMAGE>
Patent GB-2235241-A (GB)
Title: Connector for elongate members
Inventor: SMITH BRIAN DOUGLAS
IPC: F16B7/04
Filed: 1989-08-17
Abstract: A connector for joining elongate members is described comprising a sleeve (1) with two outwardly resilient projecting rectangular tabs (2) moulded in opposite sides of the wall of the sleeve (1). Each tab (2) has a raised projection (3) formed with a flat abutment surface (4) at one end, the remainder of the projection (3) having flattened side wall (3a) converging to a curved end (3b). One of the sleeve has two inwardly projecting tabs (5) joined by a flexible connector (5a) forming stops blocking one end of the sleeve. The sleeve is provided with inward projections (6) engaging apertures (7) in the elongate member (8) to enable the connector to be secured to one end of the elongate member (8) to be joined to another elongate member (9) formed with D-shaped aperture (10). The member (8) and connector sleeve are located in the end of member (9), such that the resilient tabs (2) lock the raised projections (3) into the D-shaped apertures (10). Relative axial rotation of the member (9) and the connector (1) results in decoupling of the tabs (2) from the apertures (10) owing to the bevelling of the edges (3a), (3b) of the former. <IMAGE>

Patent GB-2230145-A (GB)
Title: Limit switches with indicating means
Inventor: ROCHARD MICHEL
IPC: H01H15/10
Filed: 1990-04-02
Abstract: A limit switch includes resilient means (3) which is tensioned by the movement of an operating member (1) from a rest position and which abruptly actuates a contact carrier (9) when it moves overcentre. In the event that such abrupt movement is prevented, a transmission means such as a lever (24) is driven by the operating member (1) to produce the movement of the contact carrier (9). Indicating means such as coloured zones (101, 102, 104) on the operating member (1) and the contact carrier (9) indicate the movements of the operating member (1) and contact carrier (9). From the relative position of these zones viewed through a window in the switch casing (100), the user can adjust the positioning of the limit switch with respect to a movable actuating member. The user can also check whether the contact carrier (9) moves in response to the resilient means (3) or in response to the lever (24). <IMAGE>
